Question

answer the following questions ​

Answer 1

Answer:

Step-by-step explanation:

1. Cost of one book = 152.50 Rupees

Cost of 24 book = 152.50 x 24

                           = 3660.00 Rupees = 3660 Rupees

2. Property used = distributive

(-50) x [37+ -7] = (-50 x 37) + (-50 x -7)

-50 x 30 = -1850 + 350

-1500 = -1500

LHS = RHS

3. No. of surgeons invited for conference = 474

No. of surgeons participated= 5/6 x 474 = 395

Non participants = total - participants

                            = 474 - 395 = 79

                        section c

4. Time taken by manya = 7/9 hrs

Time taken by vaibhav = 3/4 hrs

To make denominator equal take LCM = 9 x 4 = 36

7/9 x 4/4 = 28/36 ; 3/4 x 9/9 = 27/36

therefore, manya took more time.

28-27/36 = 1/36 hrs

manya took more time than vaibhav by  1/36 hrs.
